Ifind it interesting that his comment says that working with africanized bees in Brazil requires more smoke.

Everything I have read on africanized bees thus far suggests that africanized bees respond poorly to smoke to begin with.

I talked with a Peace Corps volunteer who taught beekeeping in South America. She said they used LOTS of smoke. Typically it was a two-person operation: one person to operate the smoker and one to do the hive manipulations.
